Summary of the invention
According to the deficiencies in the prior art, the present invention proposes a kind of heat-insulation electric rice cooker, comprises a pot body, central controller, is contained in interior pot and cover cap pot cover above the pot in described in the described pot body; It is characterized in that also comprising can be to the fountain head of water spray in the described interior pot, described fountain head is arranged on the described pot cover; Described central controller comprises can control the timer module that described fountain head is regularly sprayed water.
Wherein, described fountain head is a kind of device that can spray water, and it can be the end of aqueduct, also can be to be the shower nozzle of gondola water faucet shape or to be the nozzle that only has an apopore, and shower nozzle or nozzle are connected to the water source by aqueduct.Can also be, described fountain head be the aproll dish shape that can rotate, and also is provided with on the described pot cover to drive the driver that described fountain head rotates.
According to technique scheme, since described pot cover increased can pot be sprayed water in described fountain head, thereby not only can be equably in described rice in the insulation of pot spray moisture content, make the surface of rice can be subjected to water equably, and outer surface rice can not dried up easily; Secondly because comprising, described central controller can control the timer module that described fountain head is regularly sprayed water, described like this central controller not only can move by the timing controlled water spray, and the time of water spray action can be controlled in the time period of cooking after finishing 24 hours automatically, even surpass after 24 hours thereby make to cook to finish, rice also can be preserved moisture when obtaining being incubated.By the meal in the insulation is added wet process, thereby make dry meal rice regain moisture, increase rice mouthfeel, it is longer that temperature retention time can be continued.
Further technical scheme can also be, also comprises storage tank, and described storage tank arrives described fountain head by the aqueduct diversion.
Further technical scheme can also be, described storage tank is arranged on the described pot cover or on the described pot body.
Further technical scheme can also be,
Further technical scheme can also be that the pipeline of described aqueduct is provided with booster water pump.
Further technical scheme can also be that the pipeline of described aqueduct is provided with electric control valve.
Because the present invention has These characteristics and advantage, can be applied in the heat-insulation electric rice cooker product for this reason.
The specific embodiment
Be further described below in conjunction with the structure of accompanying drawing to the heat-insulation electric rice cooker of application technical solution of the present invention.
As shown in Figure 1, a kind of heat-insulation electric rice cooker comprises pot body 1, central controller 2, is contained in interior pot 3 and cover cap pot cover 4 above the pot 3 in described in the described pot body 1.Described pot body 1 mainly forms the support shell of described electric cooker and holds described interior pot 3, described central controller 2 and electric heater etc.Described electric heater is arranged on bottom or the sidepiece of described interior pot 3.
Described pot cover 4 is provided with can be to the fountain heads 5 of water spray in the described interior pot 3; Described central controller 2 comprises can control the regularly timer module (not drawing among the figure) of water spray of described fountain head 5.Also be provided with storage tank 7 on described pot cover 4, certain described storage tank 7 also can be arranged on the described pot body 1.Secondly, described central controller 2 can also form control to described heater, electric control valve 61, motor 52 etc.
Described storage tank 7 arrives described fountain head 5 by aqueduct 6 diversions.Connected mode between described fountain head 5 and the described aqueduct 6 can be determined according to described fountain head 5 different structures.Wherein:
When described fountain head 5 is nozzle-like (not drawing among the figure), nozzle has aperture, described fountain head 5 is fixedly mounted on the described pot cover 4, mainly is to utilize hydraulic pressure to spray formed fine water droplet in the nozzle aperture to spray equably, and described aqueduct 6 need be connected to described fountain head 5 for this reason.In order to allow the nozzle of described fountain head 5 form thinner water droplet, preferably set up booster water pump at the pipeline of described aqueduct 6, not only can pressurize and also can draw water.Secondly on the pipeline of described aqueduct 6, also be provided with electric control valve 61.
When described fountain head 5 is when being aproll dish shape, described fountain head 5 is rotatably installed on the described pot cover 4, and described aqueduct 6 directly is not connected with described fountain head 5 but only water is guided on the described fountain head 5.In this structure, as shown in Figure 1, on described pot cover 4, also be provided with motor 52, described motor 52 is connected with the rotating shaft of described fountain head 5 by belt 51; Certainly, described motor 52 also can directly drive and connect or connect described fountain head 5 by reductor.When needs were sprayed water, not only described motor 52 can drive described fountain head 5 rotations, and the electric control valve 61 that is arranged on the described aqueduct 6 is also opened water supply like this.
Above-mentioned process and the time that adds water, can finish by the control of described central controller 2.Whole control process is as follows:
1. fill one case pure water to described storage tank 7, can cook then; The control of end back enters keeping warm mode cooking.
2. described central controller 2 records the temperature retention time of rice; When rice was incubated 12 hours, rice began drying, and this moment, described central controller 2 sent signal, made motor 52 startings, and motor 52 passes to rotatory force on the described fountain head 5 by belt 51, and it is rotated; Described central controller 2 also sends signal to electric control valve 61 simultaneously, electric control valve 61 is opened, water flows on the described fountain head 5 through electric control valve 61 from described storage tank 7, because described fountain head 5 is rotating, the centrifugal force that made water generates, under the effect of centrifugal force and self gravitation, water is spread across the surface of rice and the edge of interior pot, and rice just can be from new acquisition moisture like this.Add water and finish, described central controller 2 sends signal again, and described electric control valve 61 and motor 52 are stopped.
3. insulation is after after a while, and moisture can evaporate, and described central controller 2 can be according to the length of temperature retention time, and regularly the rice watering in the insulation repeats said process.
According to technique scheme, since described pot cover 4 increased can pot 3 be sprayed water in described fountain heads 5, thereby not only can be equably in described in the insulation of pot 3 rice spray moisture content, make the surface of rice can be subjected to water equably, and outer surface rice can not dried up easily; Secondly because comprising, described central controller 2 can control the regularly timer module of water spray of described fountain head 5, described like this central controller 2 not only can move by the timing controlled water spray, and the time of water spray action can be controlled in the time period of cooking after finishing 24 hours automatically, even surpass after 24 hours thereby make to cook to finish, rice also can be preserved moisture when obtaining being incubated.By the meal in the insulation is added wet process, thereby make dry meal rice regain moisture, increase rice mouthfeel, it is longer that temperature retention time can be continued.
